Patent JP-S6423627-A (JP)
Title: Frequency synthesizer
Inventor: MURAYAMA YUKIO
IPC: H03L7/18
Filed: 1987-07-17
Abstract: PURPOSE:To make phase differences between signals to a phase comparator immediately after making power supply coincident with each other, by providing a phase matching circuit which causes the phase of the signal from a variable divider to match with that of a reference signal from a synchronizing type divider by resetting or presetting the synchronizing type divider in accordance with a signal from the variable divider immediately after the power supply is made. CONSTITUTION:After a switch S1 is turned on and power supply is made, e phase matching circuit 14 receives a dividing signal from a variable divider D and a synchronizing type divider 2 is reset or preset with the dividing signal. A reference signal from the synchronizing type divider 2 and the dividing signal from the variable divider D are inputted to a phase comparator 3 in a state where the phases are matched with each other. Then a switch S0 is closed at desired timing. Therefore, the frequency of a voltage-controlled oscillator 5 does not change immediately after the power supply is turned on.

Title: Welding current control method for plural electrode high-speed rotating arc
Inventor: MURAYAMA MASATOMO
IPC: B23K9/127
Filed: 1992-07-07
Abstract: PURPOSE:To improve welding efficiency by mutually deviating phase of a welding current carried per each rotation of plural electrodes rotating arc welding to perform welding. CONSTITUTION:In electrode rotating arc welding where welding is performed while plural consumable electrode wires 1 arranged adjacently to each other arc rotated synchronously in the same rotating direction and at the same rotating speed, the number of pluses of the pulsative welding current carried per each rotation of each consumable electrode wire is made the same each and the phase of the welding current carried to these consumable electrode wires 1 is deviated mutually to perform welding. Consequently, since the product of the welding currents carried to two arcs to affect electromagnetic attraction force which causes the generation of arc blow is reduced as compared with the case where the phase is synchronized with each other, the generation of arc blow is reduced and stable welding with high efficiency can be performed with a high current.

Title: Automatic amplification factor adjustment circuit in optical sensor
Inventor: TERAMAE KATSUHIRO
IPC: H03G3/20
Filed: 1991-06-25
Abstract: PURPOSE:To provide the automatic amplification factor adjustment circuit for an optical sensor in which an amplification factor of a light receiving circuit is extremely reduced to prevent malfunction against external disturbing noise when a reflection signal from a reflection object is reduced to a degree equal to that no object is in existence. CONSTITUTION:The circuit is provided with a feedback control system 3 in which an amplitude of a pulse used to modulate a light projection beam exposed from a projector 1 is changed automatically to keep a reflection luminous quantity from an object O constant to correct a difference from the luminous quantity due to a difference from the object O. The amplification factor of the light receiving circuit 2 is controlled basically so that the amplification factor is increased to a low light receiving quantity and decreased to a high light receiving quantity. When the light receiving quantity is extremely low in a way that the light cannot be expected as the reflected light from the object O, the amplification factor of the light receiving circuit 2 is reduced to a prescribed reduction level.
Patent JP-S6073764-A (JP)
Title: Interruption controller
Inventor: SATAKE SHIGERU
IPC: G06F13/24
Filed: 1983-09-30
Abstract: PURPOSE:To obtain an interrupt controller without an interrupt processing time limit by installing an interrupt inhibit circuit which gates an interrupt signal from a serial I/O controller after receiving an interrupt inhibit command from a processing unit. CONSTITUTION:When a CPU3 outputs an inhibit command (INH)20 into an INH circuit 11 before a serial I/O controller 2 (SIO) enters a reveiving action, the circuit 11 which has received this command breaks an AND gate 12 because an INH signal is regarded as a low level. Therefore, even when the SIO2 begins the receiving action and the first character interrupt takes place, the interrupt is obstructed by the AND gate 12 and is not inputted into the CPU3. The CPU3 will not read a vector. Due to a trailing edge of the first character interrupt which is outputted by the SIO2, the INH circuit 11 then regards the INH signal automatically as a high level and releases the AND gate 12. Consequently, the subsequent interrupts which are generated by the SIO2 are inputted into the CPU3 as usual.

Title: Preventing circuit for malfunction due to unnecessary signal
Inventor: IKUTO YOSHIHIRO
IPC: G06F3/02
Filed: 1986-07-31
Abstract: PURPOSE:To preclude malfunction due to an unnecessary signal such as chattering noise by deciding the signal state of an input signal at the time of its resetting from the time continuance when the input signal is inputted. CONSTITUTION:An edge detecting circuit 20 which detects a signal edge is provided and a timer 60 measures specific times T1 and T2 from an edge generated at the change point of the signal. Then, a signal deciding circuit 40 makes an input decision when an optionally applied signal is in the same state for a constant time set by a timer 80 and when the input signal is reset, the input resetting is decided if the reset state continues for a constant time T2; and an inhibiting circuit 80 inhibits the input deciding operation of the signal deciding circuit 40 until an input resetting signal is generated after the output of the input decision signal. Therefore, when a discontinuous signal is superposed upon the signal, the state of the input signal is not generate continuously, so the signal deciding circuit 40 generates no input decision signal.
